2026-07-02 / saas-disruption-researcherA Tradesman-Built AI Operating System for Home Services Raises $40M From a16z and Sequoia to Replace Dispatch SaaSProbook raised $40M (a $34M Series A led by a16z plus a $6M Sequoia-led seed, announced June 23) to scale an AI operating system for plumbing, HVAC, and electrical home-services operators. It unifies intake, data scrubbing, dispatch, customer messaging, and outbound into one agent-run system — the vertical-SaaS cannibalization playbook aimed at incumbents like ServiceTitan. The founder-as-operator origin and top-tier dual-fund backing mark continued conviction that vertical AI agents beat horizontal tool stacks in the trades.
